7MWGT4027HW0 Whirlpool Dryer - Instructions

First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

Repair was very easy. We are in the internet age so I use it all the time to get info on how to repair any thing in the house including cars. This time it was my dryer. I typed up 'Kitchen Aid dryer has not heat'and pressed searched and PartSelect came up. Typed in the model number and looked up the comments on No Heat. They had pretty cool site that shows videos on how to repair this things too. Came to conlclusion that the THERMAL FUSE was the main problem. Ordered it and as well as the Igniter assy just to make sure and as well as save on the shipping just in case. Ordered on Sunday night and the shipped the next day. It arrived on Tuesday. Unfortunately had a little problem on the shipment. Called PartSelect and they are so awesome they shipped me new parts asap at no extra charge. Awesome Awesome! Parts came in Thursday and first installed the Thermal Fuse and BAAAM! problem solved. Did not need the igniter assembly. Now I have an extra part in storage.
To replace the Thermal fuse.
1. Disconnect Dryer from power outlet. Remove the bolts on the back panel with a 1/4" socket. I used power drill because it is much faster.
2. Locate the Thermal Fuse. Disconnect wires and remove the bolt. Slide it up and pull. Install the new one and reconnect the wires. Replace the panel and plug the dryer.

That solved my problem. It should solve yours too. The whole process was less than five minutes.

Followed electrical drawing from switch to motor, Thermal fuse was in the line and no power coming through it, removed wire and put together and tested, dryer turned on. Read statements from others at parts select and also bought thermostat because time stopped working last year. Installed both parts and cleaned dryer, works perfect including timer.

PartSelect showed seven different possibilities why the dryer wouldn't heat. I removed the two screws to remove the bottom panel and turned the dryer on and noticed that the heating element that ignites the gas was working fine. This meant that it was not getting gas so it could be the gas valve or one of the two gas valve coils which are located on top of the gas valve. I borrowed my neighbor"s ohm meter and touched the two probes on the coils terminals to check for continuity and found that one of the coils read zero. I then took both of the coils out by removing two screws and tested each coil again. One coil read 500-850 and the other read zero. This meant that it was no good so I called for the part and received it in three days. I reassembled the parts and turned the dryer on and it fired up after a few seconds. It works as good as new. The part plus shipping was less than $30. My repairman would have charged me $150-$200. While the dryer was apart I gave it a good cleaning with a vacuum and a toothbrush in delicate areas. I also removed and cleaned the lint trap housing by removing two nuts. I didn't know much about gas dryers, but thanks to PartSelect I easily fixed it myself.

Grow a second set of hands. Always unplug any appliance. Remove lint screen. remove two screws (philips Head). I took a wooden shim lightly tapped w/hammer to pop front of dryer top free. Mine worked on hinges and just flipped back til it rested against the wall. Removed two 5/16 screws inside holding face on carefully raise face section off the support clips at either side on the bottom. Pull drum out (I have the large style drum commercial size [approx.). Clean the inside free of all lint (known to be fire hazard). Sling new belt around drum. Get newly grown set of hands to hold drum in place. Pinch belt to fit between tensioner, lift tensioner and place belt around motor pulley. Spin drum couple times to make certain belt isn't twisted. Reverse dismantle proccess to put back together. Replace all parts that come with kit, you'll feel better knowing you got a new dryer, almost.

When my dryer suddenly stopped functioning, without any prior signs of pending failure, I guessed that it had to be something simple, like a fuse. I did a google search and stumbled across a forum post that described the symptoms (wouldn't turn on), and the poster said that Whirlpool recommends replacing the thermostat whenever the fuse is replaced. The reason for this is that the likely cause of the fuse burning is that the thermostat is no longer properly regulating the temperature range of the heating element.

I disconnected the power source, and then I removed the back cover, and both parts were in plain view, so I simply replaced the wires one by one.

There was no problem with lint build-up within the dryer & the exhaust vent. I removed the gas cycling thermostat & thermal fuse from system & dryer still was not operating correctly. The radiant sensor & hi-limit thermostat both seemed to be operating correctly. That left either of the two coils as the culprits. I replaced both coils & the problem was corrected.

I spent nearly an hour trying to self-diagnose the problem before I wised up and found PartSelect.com. After reading just a couple of postings I went back and tested the thermal fuse. It was bad. Other posts suggested I replace the thermostat at the same time, so I ordered both. The parts arrived within three days and the actual repair took less than 10 minutes.

Timer wasn't working on the regular cycle so I replace it with a new one from partselect. It still wasn't working so I ordered and replace the cycling thermostat, the thermal fuse I also cleaned the vent and dryer it still didn't work so I read the diagram for the electrical and found that a coil for the gas valve is line with timer. I ordered the coils for the valves, replaced both valves and tested the dryer and it work just like when I first bought the appliance.

Determining the problem was the hardest part. With multiple parts (coils,thermostats...)possibly causing similar symptoms, I narrowed it down to the two coil valves.
Un plug the dryer. Remove two screws at the base of the front panel. Turn the front panel 180 degrees to avoid disconnecting the door switch. Gas valve with coils on top are on the right in front. Remove two screws in bracket holding coils, disconnect the wires, replace with new coils and reconnect wires. One coil has 2 terminals the other has 3 no chance of crossing the wires. I used an offset/right angle screw driver for one of the bracket screws due to close proximity to the drum. A stubby phillips head will work. You can check the burner operation with the front panel off as long as the door switch is still attached. Swing the front panel around and lift back into place securing with the two screws. Dryer works fine now.

Pulled off the dispenser. Used socket set to remove bolt. Removed entire agitator out of washer. Placed both feet on bottom of agitator and then pulled up on the upper agitator. It took some muscle due to the years of washer use. I used a flat-head screwdriver to weaken the plastic clips holding down the old bearing-driven cam. Once I got the upper agitator off, the guts were easy to pull out. Then I just re-assembled with the 3 new parts (the Cam Driven, the Dog Ears, and the Bearing-Driven Cam).

I removed the two screws holding the front panel to expose the lower works and verified the heating cycle failure. After a check of the vent system, checking the sensors for continuity and coils for resistance, I retired to the 'net for support. Accepting the general consensus that the most frequent, common and likely failure to be the coils, I rechecked them with the meter and found the two pronged coil to have significantly more resistance than the three prong coil. That was enough evidence to point to the coils. While I waited for the part to arrive, I replace the vent ducting. When the parts arrived I removed the two Phillips screws holding the coils, removed the old ones, installed the new ones, replaced the bracket, put the front cover back on and in less then ten minutes clothes where drying.

JUst like a new dryer aain after all PM was complete.

First I removed the fabric softener container and set it aside. Below that, there is a plastic cover with a rubber gasket that distributes the fabric softener. I also just pulled that out and set it aside. Below that was an 11mm bolt that attached the upper and lower agitator to the drive mechanisim. The lower agitator is attached directly to the shaft and that was working properly so I knew it was't a motor or drive issue. Until it broke, the top half of the agitator sat still for a second, then it turned clockwise with the lower agitator. This helped push the clothes down to the lower part to be circulated throughout the wash cycle. Well, now the upper agitator just sat there, like it wasn't attached to anything at all. Below the aforementioned plastic cover with the rubber gasket, I found a part that had 4 plastic "teeth" that moved in and out, releasing and grabbing the inside of the upper agitator, respectively. Over time, these teeth wore down and stopped "grabbing" the ridges on the inner part of the upper agitator, causing it to stop turning with the lower agitator. I removed the 11mm bolt and tried to seperate the upper agitator from the lower agitator to replace the teeth. This part was kind of tough to get out because the plastic clips that held it in were deformed. I just had to pull hard and eventually it came apart. In the process, I broke two of the clips. I wasn't really concerned because the 11mm bolt holds everything in place anyway. After that I just swapped out the worn teeth with the new ones. I put it back together in the opposide order I took it apart and viola....good as new. And it only cost me $15 bucks.
